Compared with the traditional lateral window technique, the crestal approach reduces surgical morbidity, postoperative discomfort, and overall treatment time, while still providing the ability to regenerate sufficient bone for implant placement. Despite these advantages, a major challenge of this technique is the difficulty in detecting and managing Schneiderian membrane perforations due to limited visual access. Schneiderian membrane perforation remains the most frequent complication associated with sinus augmentation and, if left unmanaged, may compromise graft stability, increase the risk of sinus pathology, and negatively affect implant survival. Therefore, the development of reliable methods to identify and manage membrane perforations is critical for achieving predictable outcomes.

Clinical and radiographic outcomes were systematically evaluated. Preoperative assessment included measurement of the residual alveolar bone height and determination of the sinus floor angle. Each sinus was carefully examined radiographically to rule out any pre-existing pathology, such as mucosal thickening, cystic changes, or evidence of sinusitis. Intraoperative sinus membrane perforations were identified during osteotomy preparation. Management involved the placement of dehydrated amnion-chorion membrane configured in a \"waffle cone\" shape, which allowed simultaneous implant placement and bone grafting in all cases. The amount of vertical lift achieved was also measured postoperatively to quantify the effectiveness of the crestal sinus augmentation and to ensure adequate bone gain for implant placement.

However, delayed wound healing after implant placement caused by severe hypovitaminosis C has not been previously documented.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This report describes the case of a 40-year-old systemically healthy male who developed delayed wound healing after implant placement, despite having quit smoking 10 months prior to the uneventfully completed surgery and having received successful periodontal treatment for his previously diagnosed periodontitis. Focused history taking suggested possible nutritional deficiency, with subsequent blood testing revealing severe hypovitaminosis C (plasma vitamin C [vitC] level at 0.2 mg/dL).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Following oral vitC supplementation and dietary changes, a marked improvement in tissue healing was observed, and plasma vitC levels returned to within normal levels (0.8 mg/dL). Four months after surgery, vitC levels had increased to 1.2 mg/dL.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Vitamin C deficiency can lead to impaired wound healing following implant placement surgery. Supplementation and diet modification can rapidly correct the deficiency and reverse the associated clinical signs and symptoms. Identification and management of possible nutritional deficiencies requires detailed history taking and targeted blood testing, along with interdisciplinary care.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Key points: &lt;/strong&gt;Although relatively uncommon, especially in otherwise healthy patients and in developed countries, poor or delayed wound healing after dental implant placement can occur, and the underlying etiology may not be apparent. Severe hypovitaminosis C is a previously unreported cause of such poor wound healing. More focused history taking and indicated blood tests can reveal serious nutritional deficiencies, such as severe lack of vitamin C (vitC), and thus identify uncommon systemic conditions that contribute to the patient's presenting problem. Supplementation with vitC, and dietary changes when indicated, will result in rapid reversal of the signs of hypovitaminosis C and restore to normal the systemic levels of the vitamin.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Plain language summary: &lt;/strong&gt;Dental implant placement to replace missing teeth is nowadays a routine surgical procedure that results in few complications. Poor or delayed wound healing after implant placement may occur sometimes, and underlying systemic issues, such as smoking, can be one of the causes. Vitamin C, also known as ascorbic acid, is an essential human nutrient because humans cannot make it. Lack of vitamin C (vitC) can lead to a serious condition called scurvy, which presents with different signs and symptoms, including bleeding gums and poor wound healing.

The Suya method is traditionally performed freehand, which introduces risks of root damage and procedural inconsistency. A digitally guided protocol may address these limitations by enhancing safety and technical predictability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A digital workflow based on the Suya method was developed using cone-beam computed tomography (CBCT) and intraoral scanning data to generate a three-dimensional (3D) integrated model of the maxilla. Vertical and apical osteotomy lines were virtually planned between roots and in the apical region. A customized surgical template (Suya corticotomy utility template) was designed using free software and fabricated via 3D printing. Guided corticotomy was performed using a piezoelectric device, followed by controlled chisel application along both vertical and apical cuts.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;In a 32-year-old female patient, the digitally guided corticotomy was executed with high accuracy and reproducibility. Piezoelectric cortical incisions followed the preplanned paths without deviation. Chisel application along the guide-defined paths resulted in controlled fracturization. Postoperative CBCT confirmed that all osteotomies were positioned safely between roots, with no evidence of root contact or damage.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;This digitally guided Suya method provides a reproducible and biologically sound approach for performing root-sensitive corticotomy with enhanced surgical control. The use of 3D-printed guides tailored to piezoelectric instrumentation may improve safety, accuracy, and standardization of corticotomy procedures in interdisciplinary periodontal care.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Key points: &lt;/strong&gt;A digitally guided corticotomy protocol based on the Suya method enables root-sensitive osteotomy with improved surgical accuracy and safety. CBCT and IOS integration allows for precise virtual planning of osteotomy lines, which can be transferred intraoperatively using a customized 3D-printed guide (Suya corticotomy utility template). The workflow supports reproducible corticotomy in adult patients with dense cortical bone, minimizing the risk of root damage and surgical variability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Plain language summary: &lt;/strong&gt;Orthodontic treatments in adults can take a long time due to slower bone remodeling. To speed this up, surgeons may perform a procedure called corticotomy, where small cuts are made in the bone around the teeth to stimulate faster movement.

The average follow-up was 4 years and all implants demonstrated 100% survival and success rates. No failures or complications occurred, except for minor prosthetic chipping in one patient, easily repaired. Postoperative pain was minimal, and patients reported improved confidence, speech, and mastication.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;The present technique presents certain challenges and limitations. The surgical approach requires advanced expertise in basal bone anchorage, meticulous case selection, and precise execution to avoid complications.

Three-dimensionally (3D) printed PCL meshes have demonstrated the ability to conform to the defect morphology, providing stable space maintenance and promoting angiogenesis during hard tissue healing. While PCL has shown promise across various medical applications, clinical studies evaluating its effectiveness for hard tissue augmentation in implant dentistry remain limited.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This case study included three patients with four implants placed simultaneously with lateral bone augmentation using thermally shaped and trimmed PCL mesh and autogenous bone graft. Cone-beam computed tomography scans were obtained preoperatively, immediately post-augmentation, and at 1-year follow-up. Voxel-based registration was used to standardize measurements, evaluating bone width changes at the implant shoulder level, and 1, 3, 5, and 7 mm apical to the implant shoulder.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;At 1 year, all implants remained clinically stable with no adverse events or significant crestal bone loss.

The authors describe a new technique for the reconstruction of intra-bony vertical defects caused by peri-implantitis, which requires the removal of the prosthetic superstructure to have better access to the surgical site, in order to perform the defect debridement and the implant surface decontamination and detoxification, before placing the reconstructive biomaterials.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A 2 mm high cap screw was connected to the implant with the aim of not letting a cross-linked collagen membrane to collapse over the implant threads. This membrane covered the implant and the whole defect, filled with a porcine bone graft wet with hyaluronic acid. A second membrane, made of dense polytetrafluoroethylene (dPTFE), was placed over the previous one and left exposed, avoiding a second intervention for its removal, which occurred after a 5-week healing time by grasping the membrane with forceps and removing it with a gentle tug. After cap screw removal, it was possible to insert an healing abutment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The augmented bone remained stable 2.5 years after prosthetic superstructure re-insertion.

A review of the literature indicates that the bilaminar technique is a more reliable surgical approach for achieving cosmetic results in a single operation. An 8-year follow-up case report supports this finding, detailing a procedure that involved muco-abrasion of the lesion followed by a sliding pedicle flap.</p><p><strong>Plain language summary: </strong>An amalgam tattoo is an iatrogenic lesion associated with esthetic concerns. This paper reviews treatment options for this issue, analyzing 18 relevant publications from an initial search of 209. Additionally, a case report details the treatment of a 47-year-old female patient with an amalgam tattoo on her upper right premolars. After muco-abrasion to remove the lesion, a plastic surgery procedure with a connective tissue graft from the palate was performed. At the 8-year follow-up, the gingival color and texture matched the surrounding tissues, the periodontal structures appeared healthy, and the patient was satisfied with the results.</p>","PeriodicalId":55950,"journal":{"name":"Clinical Advances in Periodontics","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144746123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
